CONCRETE-CASING.

To all whom it may concern: k 7

Be itknown thatcI, JOHN W. KENNY, a

citizen of the United States, residing at the city of New York, borough of Brooklyn,

Kings county, in the State of New :York,

7 has for its object more particularly to providev asimple, efficient and reliable casing which may readily be extended to anycdesired height and which will properly insure the alining of the several parts when the same are arranged. in end to end relation one upon the other.

, Further, sai H I to provide a casing consisting of a plurallty -of tubular elements so arranged and constructed thatthe same may be disposed one -.-upon the other with their adjoining ends or edges in contact, and said ends or sections; held against lateral movement relatively to,

each other in order to produce a continuous casing having a smooth, unbroken, outer surface. j, p j a Further, said invention has for its object 7 I to provide a casing consisting of a plurality tubular section.

of tubular elements, each provided atrone end with a sleeve section adapted to be fitted into the opposite end of a corresponding Further said invention has for its object to provide a casing consisting of a plurallty of tubular sections each PIOVlClGd at one end with a short sleeve section arranged partly within and partly without the tubular section and having the portion thereof arranged within said tubular section permanently secured thereto.

To the attainment of the aforesaid objects and ends, my invention consists inthe novel details of construction, and in the combina-- tion, connection and arrangement of parts hereinafter more fully described, and then pointed out in the claims. I In the accompanying drawings forming part of this specification, wherein likenumerals ofreference indicate like parts, Figure 1 is a side vlew showing aportlon of a tubular sectlon' with a sleeve member secured in one end thereof; Fig. 2 is a section taken on the line 22 of Fig. 1, looking in V the direction of the arrow; Fig. 3 is a side view showing two tubular sections disposed d invention has for its object Specification of Letters Patent.

one upon the otherv and maintained in position by the sleeve member; and Fig.4 is a central vertical section. a

In said drawings 10 designates a tubular casing section which may be of any desired fdiameterand'length,and 11 denotes a similar section arranged in position below the casing section first named.

12 denotes a short sleeve section having an outer diameter slightly smaller than the interior diameter of said casingasection 10 in order that the same may be readily fitted into one end of said casing section. The sleeve section 12 may be of any desired length, but by preference I arrange the same tion 10' with a view to resisting anylongitudinal strain or pressure. I have therefore devised an effective methodof securing a -sleeve section withina casing section which is notonly inexpensive but also easy-to carry into effect. To secure said sleeve section 12 within the casing section 10 I first adjust the sleeve section and the casing section to which it is to be secured upon a suitable mandrel and then punch equally spaced semicircular projections or indentations 13 in said casing section and cause the inner rounded portions of said indentations or projections to be driven into the outer surface of the sleeve section 12, and thus serve to hold said sleeve section permanently and rigidly secured therein. 7

By means'of my invention, I am thus enabled to provide a casing composed of a plurality of tubular sections, each of which is provided at one end with a sleeve'12. The

said casingsections do not, therefore, require a separate or independent guide or sleeve which must first be inserted between each pair of pipe ends in order to maintain the contiguous ends thereof in proper end to end relation and produce a casing having a perfectly smooth, unbroken, outer surface. Further, by reason of my construction, I am enabled to produce a joint for the casing sections which is not apt to get out of order I adj oining casing section, theprojecting por- 5 hold the several parts duly secured togethery substantially as specified.
